I've got another brief warm up stint DJ set in December - mostly old dancehall stuff from the 80s, but I like to play some up to date JA stuff as well - especially do-overs of old riddims with new vocals on them (like Digital B's etc) or new reggae-ish riddims rather than flat out bashment (I really liked "Big Up" on Taxi earlier this year). Funky stuff with nice basslines...

check out new 7" on Frenchies Maximum Sounds imprint:
Jnr Kelly - Tough Life
Lukie D - Too Long
rhythm is a relick of Studio One `Al Campbell - Take A Ride`, there`s a 3rd cut but it went outta stock, can`t remember who by either.

also, on Mister Tipsy:
Bunny Ruggs - Marcus Garvey
Natty King - Natty Bongo
Queen Ifrica - Story Of My Life
these are on a relick of Spears `Marcus Garvey` rhythm, to me its a little on the slow side but pitch it up a few notches and it works fine.

those tracks on the rebuilt "stop that train" riddim including one from morgan heritage (i would call it "hail up the lion" but its actually titled something different), one from shaggy (dont laugh) and one called jamaican jiggers by someone id not heard of. all are A1 and the riddim is smashing.

Was beaten to the draw on Natty King - Natty Bongo and the Return/Stop That Train/Draw Your Brakes rhythm. But the version I have of the latter is 'Non Genuine' by Degree (VP Records) - it's pure class and already on my December playlist.

I can also recommend a couple of recent 7s from Joseph Cotton - Pull Dem Down (Heartical) on the Ali Baba/Natty Chase The Barber rhythm, and Wicked Running (Education), a version of Cuss Cuss.

Other rhythms back in vogue include 007/Shanty Town(!) such as Gentleman's 'Rumours' (Pow Pow) and, even more surprising - though a couple of years old now - Ras Michael's 'None a Jah Jah Children No Cry'. My own favourite of that one is Spectacular's Baby Mother on the back of Junior Kelly's Black Am I, but Ernie B usually has plenty of other versions.

And for a new roots rhythm (at least I think it's new) - Ranking Joe's World in Trouble (Fleximix), a Twilight Circus Production.

Don't know what your crowd will be like, but those all went down well where I am. Good luck!
